Transcription
Phases
Silver tungstate occurs in three polymorphic phases: orthorhombic (α), hexagonal (β) and cubic (γ).[2] α-silver tungstate is thermodynamically stable, while β- and γ-silver tungstate are metastable.[5]
Synthesis
Silver tungstate is synthesised through the following reaction between silver nitrate and sodium tungstate, producing sodium nitrate as a byproduct:[2]
